We are the KeystoneJS to Agility CMS migration experts

The biggest challenge with KeystoneJS is that it hands you all the responsibility that a managed CMS would normally handle. Deployment is entirely on you, and the documentation around production hosting, Docker configuration, and scaling is thin. We've seen teams struggle to go from a smooth local development experience to a reliable production setup, especially if they don't have dedicated DevOps support. The admin UI Docker image alone can balloon to over a gigabyte, which is a headache for containerised deployments.

The community around Keystone is significantly smaller than competitors like Strapi or Payload. That means fewer tutorials, fewer plugins, and slower answers when you hit an edge case. The ecosystem of ready-made integrations is almost non-existent, so you'll be building most things from scratch. For an agency working on client projects with deadlines, that time cost adds up quickly.

Content editors also tend to have a harder time with Keystone compared to more polished alternatives. The admin UI is functional but feels utilitarian, and non-technical users often need more onboarding than you'd expect. There's no visual editing, no preview infrastructure, and no real content workflow features like drafts, publishing schedules, or approval chains without building them yourself. If your client's content team needs a CMS they can pick up and run with, Keystone usually isn't the answer.

Agility CMS is one of the few headless CMS platforms that genuinely tries to bridge the gap between developer freedom and editor autonomy. The standout feature is built-in page management, something most headless CMS tools completely ignore. Editors can create and manage pages, control the sitemap, handle SEO fields, and arrange modular components on pages without needing a developer to wire everything up. That alone saves us a ton of back-and-forth on client projects.

The Next.js integration is solid and well-maintained. The SDK handles page routing, preview mode, and image optimization out of the box, and getting a starter site running takes minutes rather than hours. The content modeling interface is intuitive enough that even non-technical clients can understand and extend models without hand-holding, which is rare in the headless space.

Support is genuinely excellent. The team is small enough that you get real humans who know the product inside out, not a ticket queue that disappears into the void. For agencies that need to move fast and hand projects off to client teams, that responsiveness matters. The API request limits are generous too, with high request allowances across all plans, so you're not constantly worrying about overage charges like you would with some competitors.

We also appreciate that Agility takes a pragmatic approach to headless. It doesn't try to be everything, but it does the core CMS job well and stays out of your way when you need to build custom functionality around it.
